B.Tech(EC) final year project on Robotic Arm

My name is fahad. for any query u can mail me on "NO EMAIL ID SHARING"In our project we tried to emulate and develop a prototype of a human arm which is almost similar in functioning and normal working behavior. In this project our robotic arm movement is streamed in 4 ways just simulating the behavior of human arm. For controlling the whole operation we are using the DTMF frequencies sent by user to the processing circuitry inside the arm.Our processing circuitry based of Atmel 89c52 microcontroller which is 8 bit microcontroller with maximum clock frequency 12 MHz which is providing sufficient speed of execution.Four shos motors of scalable torque to control the overall operation and movement are used
